Nebulae glow because they are made up of gas and dust particles that are illuminated by nearby stars. These particles scatter and reflect starlight, creating the glowing appearance. Additionally, some nebulae may also emit light due to processes such as ionization or radiation.

What is the difference between a emission nebula and a reflection nebula?
Emission nebula glow and reflection nebula reflect the light form other stars
Why doesn't the Horsehead Nebula glow like other nebulae?
Horsehead Nebula doesn't glow like other nebulae because it is older than other nebulae and was probably a lot smaller. In addition, Horsehead Nebula is farther away from the Earth than other nebulae, so it may seem that it doesn't glow as bright as other nebulae. No, this isn't right! The horsehead nebula doesn't glow for one reason - it isn't illuminated by any stars whose energy is enough to make the gas shine. That's the only difference between a 'bright' diffuse nebula (like M42) and a 'dark' one like the Horsehead or the Coalsack. M42 (the Orion nebula) is bright because there are several hot, energetic stars embedded inside it, and which cause it to 'shine'.
What process makes an emission nebula glow?
Emission nebulae glow due to the ionization of their gases by energetic radiation from nearby hot stars. These stars release ultraviolet light that strips electrons from atoms in the nebula, causing the atoms to recombine and emit light at specific wavelengths, creating the colorful glow seen in these nebulae.
What Creates a planetary nebula?
A planetary nebula is created when a low- to medium-mass star reaches the end of its life cycle and sheds its outer layers of gas into space. This process exposes the hot core of the star, which emits ultraviolet radiation that causes the surrounding gas to glow and form a colorful nebula.
What does the core of a star do when it blows its surface into space to form a planetary nebula?
When the core of a star blows its surface into space to form a planetary nebula, it sheds its outer layers of gas, exposing the hot, dense core of the star called a white dwarf. The white dwarf emits ultraviolet radiation that ionizes the ejected gas, causing it to glow and form the planetary nebula.

What color will an interstellar gas cloud composed of hydrogen glow?
It all depends on how close stars are to the cloud, and how intense those stars radiate energy. A nebula will glow with a blue colour if it simply reflects starlight (the blue is from the same mechanism our sky is blue, from the scattering of light). This occurs when a nebula is too far from stars, or the stars are too cool to generate enough radiation to ionize the hydrogen. Nebula will glow red if they are close enough to stars to absorb energy - that energy is re-emitted by the nebula as red (from the ionization of the hydrogen, which then glows red).
Why are some nebula's hard to see?
"although some nebulas glow or reflect starlight, others absorb light and so are too dark to see."

What is hot nebula?
A hot nebula is a cloud of gas and dust in space that emits strong radiation, usually in the form of ultraviolet or X-ray wavelengths. These nebulae are often associated with regions of active star formation or with the remnants of massive stellar explosions, such as supernovae. The high temperatures in hot nebulae lead to the ionization of the gas within them, causing them to glow brightly.
What type of nebulae formation is lit from within?
The type of nebulae that is lit from within is known as an emission nebula. These nebulae glow due to the ionization of gas and dust by the intense ultraviolet radiation emitted by nearby hot stars. As the radiation excites the atoms in the surrounding gas, they emit light at various wavelengths, creating vibrant colors. Examples of emission nebulae include the Orion Nebula and the Lagoon Nebula.
What is a mass of gases dust particle s and stars that are located in space?

What part of galaxy is the horsehead nebula at?
The Horsehead Nebula is located in the Orion constellation, specifically within the Orion Molecular Cloud Complex. It lies approximately 1,500 light-years away from Earth and is part of the Milky Way galaxy's Orion Arm, which is a minor spiral arm. The nebula is a region of star formation, characterized by its distinctive dark silhouette against the background glow of ionized gas and nearby stars.
What type of nebula is the Stingray Nebula?
The Stingray Nebula (Hen 3-1357) is a planetary nebula. (The youngest known).
